摘　　要：提出了计算覆盖多种材料复杂目标的激光雷达散射截面的可视化方法.使用颜色标签建立含材料信息的目标模型,通过颜色标签成像计算目标的单站激光雷达散射截面,附加双向遮挡成像计算目标的双站激光雷达散射截面.讨论了目标覆盖不同材料及用蒙特卡罗方法模拟表面涂漆脱落情况下的激光雷达散射截面的差异.结果表明,计算方法直观、快速,具有实际应用价值.The visualizing calculation method of LRCS of multi-material coated complex object is presented. The model containing material information is made by the color flag. The LRCS of the monostatic of an object is calculated by color flag imaging and that of the bistatic is calculated by additional bidirectional shading imaging. Then, the results of LRCS of the object coated with various materials and the paint rubbed off of the surface simulated with the Monte Carlo method are discussed. It is shown that the calculation method is visualized quickly and is practical.
